An experimental and systematic insight into the temperature sensitivity for a 0.15-µm gate-length HEMT based on the GaN technology

Mohammad Abdul Alim, Christophe Gaquière, Giovanni Crupi

Presently, growing attention is being given to the analysis of the impact of the ambient temperature on the GaN HEMT performance. The present article is aimed at investigating both DC and microwave characteristics of a GaN-based HEMT versus the ambient temperature using measured data, an equivalent...

Towards III-V semiconductor-based artificial graphene

Nathali. A. Franchina Vergel, L. Christiaan Post, Davide Sciacca, Maxime Berthe, Francois Vaurette, Yannick Lambert, Dmitri Yarekha, David Troadec, Christophe Coinon, Guillaume Fleury, Abhishek Juyal, Julien Renard, Tao Xu, Ludovic Desplanque, Xavier Wallart, Daniel Vanmaekelbergh, Christophe Delerue, Bruno Grandidier

We present the fabrication and characterization of III-V semiconductor-based samples designed to mimic 2D material electronic properties thanks to a nanometer-scale honeycomb potential. STM/STS results demonstrate that a well reconstructed surface is recovered after processing and that the...

Temperature-sensitivity of two microwave HEMT devices: AlGaAs/GaAs vs. AlGaN/GaN heterostructures

Mohammad Abdul Alim, Abu Zahed Chowdhury, Shariful Islam, Christophe Gaquière, Giovanni Crupi

The goal of this paper is to provide a comparative analysis of the thermal impact on the microwave performance of high electron-mobility transistors (HEMTs) based on GaAs and GaN technologies. To accomplish this challenging goal, the relative sensitivity of the microwave performance to changes in...

Coplanar waveguides on BCB measured up to 760 GHz

Nicolas Zerounian, Walid Aouimeur, Anne-Sophie Grimault-Jacquin, Guillaume Ducournau, Christophe Gaquière, Frédéric Aniel

The integrated THz pattern over any MMIC appears to be a good opportunity to enclose calibration kit suitable for accurate measurements. An original technology based on polymer has been developed. Sub-millimeter single-mode conductor-backed coplanar waveguides using benzocyclobutene polymer and...

Evaluation of an antenna selection strategy for reduced massive MIMO complexity

Frédéric Challita, M. Lienard, Davy Gaillot, Jose-Maria Molina-Garcia-Pardo

Massive Multiple-Input Multiple-Output (MIMO) is emerging as one promising technology for the fifth generation (5G), but the hardware and software complexity arising from the sheer number of transmitting elements is a bottleneck. Antenna selection strategies have been reported as an appealing...

Facile synthesis of fluorine-free, hydrophobic, and highly transparent coatings for self-cleaning applications

Abderrahmane Hamdi, Julie Chalon, Pascal Laurent, Benoit Dodin, El Hadj Dogheche, Philippe Champagne

Non-fluorinated coatings have recently emerged as a new approach to avoid contamination on transparent surfaces. This research work concerns the synthesis of highly transparent, hydrophobic, durable, and self-cleaning coatings as an alternative to fluorine-based coatings used on glass. The...

Abnormal topological refraction into free medium at sub-wavelength scale in valley phononic crystal plates

Linyun Yang, Kaiping Yu, Bernard Bonello, Bahram Djafari-Rouhani, Wei Wang, Ying Wu

In this work we propose a topological valley phononic crystal plate and we extensively investigate the refraction of valley modes into the surrounding homogeneous medium. This phononic crystal includes two sublattices of resonators (A and B) modeled by mass-spring systems. We show that two edge...
